Description
Technical field
The utility model relates to a kind of oil cylinder guide piece, refers in particular to a kind of oil cylinder guide piece of electronic-hydraulic servo pressure testing machine.Belong to scientific measurement Instrument technology field.
Background technology
Pressure testing machine is mainly used in the compressive strength test of the building materialss such as brick, cement mortar and concrete, is also usually used in the Mechanics Performance Testing of other materials.At present, in experimentation, rotate for fear of oil cylinder the error that experimentation is brought, electronic-hydraulic servo pressure testing machine has adopted external ram guiding mechanism as shown in Figure 5, its concrete structure is that vertical guide pole 3a is installed in the outside of crossbeam, horizontally-guided plate 4a is installed on the piston 1a of oil cylinder 1, and horizontally-guided sleeve-board is contained on guide pole, in the time of piston up-down, horizontally-guided plate is synchronized with the movement up and down along guide pole, has eliminated oil cylinder and has rotated the error that experimentation is brought.But this structure, because needs are installed guide pole and horizontally-guided plate on testing machine, need to occupy certain space, and assembling and when maintenance also more difficult.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oil cylinder guide piece of electronic-hydraulic servo pressure testing machine, need just can not prevent at complete machine arranged outside guide pole the rotation of oil cylinder.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of oil cylinder guide piece of electronic-hydraulic servo pressure testing machine, comprise base and the crossbeam that is positioned at base top, 4 root posts are installed between described base and crossbeam, on described crossbeam, oil cylinder is installed, the affixed top board in piston below of described oil cylinder, described top board, between four columns, is characterized in that:
Four angles of described top board are all provided with guide holder, and the surface of the relative column of each guide holder is installed with guide tile, and described guide tile is close on column side face.
That the guide holder on described top board on four angles is along the diagonal setting of top board as further improvement.
Further again, the surface that described guide tile and column fit is circular arc, matches with column periphery shape.
Principle of work of the present utility model is, guide holder and guide tile form the guiding mechanism of oil cylinder, because this guiding mechanism and top board are fixed together, guide tile on four angles of top board is close to respectively column inner side, by guide tile and guide holder, top board forms the structure of front and back and left and right full symmetric, top board can only move up and down and can not rotate along column, because piston and the top board of oil cylinder are fixed together, therefore oil cylinder also can only move up and down along the direction perpendicular to workplace, and can not rotate.
With existing external ram guiding mechanism, oil cylinder guide piece of the present utility model does not need to occupy the space outside complete machine again, and compact conformation is easy to maintenance.This device is convenient to the assembling with other parts of complete machine, has promoted reliability and accuracy when electronic-hydraulic servo pressure testing machine is tested simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done to further non-limiting description and elaboration:
In conjunction with Fig. 1 to Fig. 4, a kind of oil cylinder guide piece of electronic-hydraulic servo pressure testing machine, comprise base 8 and the crossbeam 2 that is positioned at base top, 4 root posts 6 are installed between described base and crossbeam, oil cylinder 1 is installed on described crossbeam, the affixed top board 5 in piston 1a below of described oil cylinder, described top board is between four columns, lower platen 7 is installed on base, four angles of described top board are all provided with guide holder 4, the surface of the relative column of each guide holder is installed with guide tile 3, and described guide tile is close on column side face.
That the guide holder on described top board on four angles is along the diagonal setting of top board as further improvement.In operational process, top board can not produce skew at fore-and-aft direction and left and right directions.Can improve like this stability and the accuracy of oil cylinder operation.
Preferred scheme is that a side of the relative column of described guide tile is arcuate surface, matches with column periphery shape.Certainly, a side of the relative column of guide tile can be made up of three rectangular surfaces, and now the angle between adjacent rectangle face is 120 °.
Principle of work of the present utility model is, guide holder and guide tile form the guiding mechanism of oil cylinder, because this guiding mechanism and top board are fixed together, guide tile on four angles of top board is close to respectively column inner side, by guide tile and guide holder, before and after top board forms, with the structure of left and right full symmetric, top board is by being limited between four columns tightly, in operational process, fore-and-aft direction and left and right directions can not produce skew.Can only move up and down and can not rotate along column, because piston and the top board of oil cylinder are fixed together, therefore oil cylinder also can only move up and down along the direction perpendicular to workplace, and can not rotate.
With the existing external ram guiding mechanism shown in Fig. 5, oil cylinder guide piece of the present utility model does not need to occupy the space outside complete machine again, and compact conformation is easy to maintenance.And this device is convenient to and the assembling of other parts of complete machine, reliability and accuracy when electronic-hydraulic servo pressure testing machine is tested have been promoted simultaneously.
These are only the utility model preferred embodiment, not in order to limit scope of the present utility model, every simple, equivalence of doing according to technical solutions of the utility model changes and decorates, within all falling into the protection domain of the utility model claim.
